"The addition of Accumuli will enable us to provide a wider and more comprehensive range of security solutions and services,” commented NCC Group CEO Rob Cotton who presented it as a complementary match.

“Customers are now looking for the type of 24/7 operational security support and incident management offered by Accumuli in addition to our consulting capabilities.”

The firms had already bid jointly on a number of deals something that had underlined a good fit between the two firms, he said. Cotton cited the need to expand the range of services NNC Group offered to meet rising demand as being an important motivation.

“The acquisition provides an opportunity to develop our core consulting business across a wider customer base.”

Previous acquisitions for NCC Group have included US-based Matasano Security, bought for around £8.4 million in 2012. In the same year the firm wrote off a reported £900,000 after a SAP upgrade forced it back to an older version.
